Police have released a CCTV image of a 12-year-old girl who has not been seen since Tuesday.
Suada Gashi, of Lewisham, south London, was last seen leaving Victoria coach station at 12.40 BST on 2 April, after getting the coach from Birmingham.
She was staying with her adult sister in Birmingham before her disappearance, but later told a family member on Skype she was back in Lewisham.
Metropolitan Police said Suada had her mother's Post Office bank card on her.
The card was used on Tuesday in Birmingham city centre and again the following morning.
Suada, who is known in Elephant & Castle, Croydon and Lewisham, is slim, of Mediterranean appearance with very long black hair and looks older than her age, police said.
In the last CCTV image of Suada, she was wearing beige boots, a dark-coloured coat and is carrying a coloured shoulder bag or backpack.
